Question

1. There is a rubber ball and a stone ball of same size. If both balls are at rest:
(1 mark)
(a) Rubber ball has more inertia than stone ball
(b) Stone ball has more inertia than rubber ball
(c) Both have same inertia
(d) None of these​

Answer 1

Answer:

C

Explanation:

Because both have same inersia

Answer 2

Answer:

(b) Stone ball has more inertia than a rubber ball

Explanation:

A stone ball has more inertia than a rubber ball because Inertia is directly proportional to the Mass of an Object. And we know that a stone ball has more Mass than a rubber ball. So the Inertia of a stone ball is more than a rubber ball.

Newton's first law of motion states that "An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force." Objects tend to "keep on doing what they're doing." In fact, it is the natural tendency of objects to resist changes in their state of motion. This tendency to resist changes in their state of motion is described as inertia.
